Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and particularly relates to a sealing structure for the wire outlet of a power cabinet. Background Art

[0002] A distribution box assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements to form a low-voltage power distribution device. Currently, according to different installation methods, distribution boxes can be divided into two types: vertical distribution boxes and wall-mounted distribution boxes. Both types of distribution boxes are provided with inlet and outlet openings at the top or bottom of the box body.

[0003] Currently, the existing sealing structure for the wire outlet of a power cabinet (such as publication number: CN214957845U) discloses a sealing structure for the wire outlet of a power cabinet to prevent rodent damage, including a distribution box body. The front wall surface of the distribution box body is movably installed with a switch door through a hinge. An outlet opening for wire release is provided on the outer wall surface of the distribution box body. Clamping grooves are provided on both sides inside the outlet opening. An installation bottom block is arranged inside the outlet opening. The installation bottom block is a block with a concave structure. A wire arranging board for arranging wires is fixedly installed on the inner bottom surface of the installation bottom block. Rectangular installation grooves are provided on both side wall surfaces of the installation bottom block. A first fixing groove is arranged in the installation groove. A swing arm is arranged in the first fixing groove. By providing a swing arm and a clamping block, the entire installation bottom block blocks the outlet opening completely, effectively preventing various animals such as mice, cockroaches, and moths from easily entering the power distribution cabinet through the wire routing opening.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems:

[0005] 1. Poor applicability and ineffective sealing: When the existing sealing structure for the wire outlet of a power cabinet is in use, since the number and shape of the wire grooves on it cannot be changed, only when cables are installed in all the wire grooves can the avoidance effect be ensured. However, when there are no cables in some wire grooves, voids will be formed, and at this time, the outlet opening is in an incompletely sealed state (cockroaches, moths, etc. can enter the power cabinet through these gaps). Secondly, since the thickness and shape of different cables are different, the same fixing method cannot completely seal the outlet opening, resulting in poor use effect of the device and inability to adapt to various situations;

[0006] 2. Complicated cable fixing: When the existing sealing structure for the wire outlet of a power cabinet is in use, in order to stably fix the cables, bolts need to be used for reinforcement. However, when adjusting the wires, the bolts need to be removed first and then reinstalled. This process is not only complicated but also takes a lot of time and effort. Secondly, it is also very easy to affect other cables. Therefore, we propose a sealing structure for the wire outlet of a power cabinet. Summary of the Invention

[0007] (1) Technical Problem to be Solved

[0008] In view of the deficiencies of the prior art, the present invention provides a sealing structure for the cable outlet of a power cabinet, which solves the technical problems that the existing sealing structure for the cable outlet of a power cabinet has poor applicability, cannot achieve effective sealing, and the cable fixing is cumbersome during use.

[0009] (2) Technical Solution

[0010] To achieve the above object, the present invention is realized through the following technical solutions:

[0011] A sealing structure for the cable outlet of a power cabinet, including a distribution box body for storing power devices, and a sealing component for sealing the cable outlet on the distribution box body. There are two groups of sealing components, and the two groups are corresponding up and down, that is, the cables entering and leaving the distribution box body are fixed simultaneously from the upper and lower ends to form a "clamping" state:

[0012] The distribution box body, in which power components are installed;

[0013] The sealing component is installed on the distribution box body, and the sealing component is used to seal the cable outlet, block the gap between the cable outlet and the cable, and prevent sundries or insects such as cockroaches and moths from entering the interior of the distribution box body;

[0014] Among them, the sealing component includes a fixing plate, and a plurality of movable columns are inserted into the interior of the fixing plate. The plurality of movable columns are arranged in a rectangular array, and a compression spring is installed at the top of each movable column. The compression spring is always in a compressed state, which can push the movable column towards the cable outlet direction, so that the movable column "clamps" the cable entering and leaving the cable outlet, and blocks the gap between the cable outlet and the cable;

[0015] The movable column is connected to the fixing plate through the compression spring, and the elastic force received by the movable column is always towards the cable outlet direction, so that the movable column can stably press on the outer wall of the cable and adaptively change according to the contour of the cable, thereby improving the fitting degree between the movable column and the cable. As Figure 10 shown, it can surround the outside of the cable to ensure that the sealing component can.

[0016] Preferably, the number of the sealing components is two groups, and the two groups of sealing components are respectively located on the upper and lower sides of the cable outlet, so as to "clamp" the cable located inside the cable outlet from the upper and lower directions;

[0017] Among them, the movable columns inside the two sealing components are opposite up and down and fit each other, and respectively squeeze the upper and lower surfaces of the cable, so as to form a shape opposite to the cable up and down.

[0018] Preferably, a plurality of partition plates are equidistantly installed at the front end of the fixing plate, and the partition plates are located between two adjacent movable columns. The adjacent two movable columns are separated by the partition plates to avoid mutual influence and also limit the telescopic direction of the movable columns.

[0019] Among them, when the movable column is not stressed, the length of the compression spring is less than the length of the partition plate, so as to prevent the movable column from separating from the fixing plate in the natural state, thereby ensuring the stability of the movable column during use.

[0020] Preferably, a cover plate is installed at the front end of the fixing plate, and the top of the cover plate is hinged to the top of the fixing plate, and the bottom is connected to the fixing plate by bolts, which is used to limit the movable column in the fixing plate. At the same time, when the movable column is installed or repaired, only need to open the cover plate to observe the workpiece inside the fixing plate, which is convenient for repair and adjustment.

[0021] Preferably, the extrusion part includes a connecting rod and a pressing rod that are hinged to each other. The pressing rod is inclined towards the direction of the wire outlet, so that the pressing rod can stably press on the cable. And when the cable is pulled outwards, it can hook the cable to prevent the cable from being easily pulled.

[0022] Among them, a spring piece is installed on the side wall of the connecting rod, and the spring piece is attached to the pressing rod, providing a downward pressing force for the pressing rod, so that the pressing rod presses on the cable under the action of the force, and the pressing rod stops pressing when it fits with the outer wall of the cable, so as to correspond to the outer wall of the cable, as Figure 11 shown, completely wrapping the cable.

[0023] Preferably, the end of the spring piece facing the pressing rod is arc-shaped and fits with the outer wall of the pressing rod to provide a downward pressing force for the pressing rod, and the other end is fixedly connected to the connecting rod to keep the position of the spring piece constant.

[0024] Among them, magnets are installed inside both the pressing rod and the spring piece, and the pressing rod and the spring piece are attracted to each other through the magnets, so that the pressing rod can always fit with the spring piece, facilitating the synchronous movement of the two.

[0025] Preferably, the top of the connecting rod is connected to the movable column, and the connecting rod and the movable column have the same specifications. By combining the extrusion part and the sealing component, the movement range of the pressing rod can be increased, and at the same time, the outward movement of the cable can be effectively prevented.

[0026] Preferably, the rear end of the sealing component is connected to a fixing component, and the fixing component is used to connect the sealing component to the wire outlet to maintain the stable position between the sealing component and the wire outlet.

[0027] Among them, the fixing component includes a sliding rod, and a sliding groove is opened on the side of the sliding rod away from the sealing component. Two limiting hooks are installed inside the sliding groove, and the two limiting hooks are connected by a spring.

[0028] The spring between the two limiting hooks is always in a compressed state. Therefore, when the two limiting hooks are placed into the wire outlet, the two limiting hooks can be separated from each other under the action of the spring, so as to hook the wire outlet, making the fixing component connected to the wire outlet. At this time, the sealing component connected to the fixing component is fixed together on one side of the wire outlet.

[0029] Preferably, a positioning seat is installed at the rear end of the sealing component, and a lead screw is installed inside the positioning seat;

[0030] Wherein, a threaded barrel is connected to the inside of the positioning seat through a bearing, and the threaded barrel is sleeved outside the lead screw, and the two are connected by threads. Therefore, by rotating the threaded barrel, the lead screw can extend out (or retract into) the positioning seat. Since the sliding rod is fixed to the wire outlet through the limiting hook, when the lead screw expands and contracts, the sealing component can be driven to move up and down synchronously, so as to adjust the position of the sealing component and the fitting degree between the two sealing components.

[0031] Preferably, two guide rods are installed outside the sliding rod, and the guide rods are inserted into the positioning seat;

[0032] Wherein, the two guide rods are respectively located on both sides of the lead screw, and the guide rods are parallel to the lead screw, thus ensuring the stability of the expansion and contraction direction of the lead screw and avoiding the situation of deviation.

[0033] (III) Beneficial effects

[0034] 1. Since a plurality of movable columns arranged side by side are used to block the wire outlet, and a spring is installed at the top of the movable column, the technical problems that the sealing structure of the existing wire outlet of the power cabinet has poor applicability and cannot achieve effective sealing during use are effectively solved. Furthermore, effective sealing of the wire outlet is realized, and at the same time, it can also be applicable to cables of different shapes and sizes.

[0035] 2. Since the connecting rod and the pressing rod that are mutually connected are used, and a spring piece is installed on one side of the connecting rod, the technical problems that the sealing structure of the existing wire outlet of the power cabinet has poor applicability and cannot achieve effective sealing during use are effectively solved. Furthermore, the sealing of the wire outlet is realized, and at the same time, it can also be adjusted according to the number and shape of the cables for applicability.

[0036] 3. Since the fixing component is used to drive the movable column to move up and down, the technical problem that the cable fixing is cumbersome in the existing sealing structure of the wire outlet of the power cabinet during use is effectively solved. Furthermore, the extrusion and fixing of the cable are realized to prevent the cable from being pulled, and at the same time, it can be freely opened or closed according to needs.

[0050] Embodiments of the present application provide a sealing structure for the cable outlet of a power cabinet, which solves the technical problems of poor applicability, ineffective sealing, and cumbersome cable fixing in the existing sealing structure for the cable outlet of a power cabinet. When the existing sealing structure for the cable outlet of a power cabinet is in use, since a plurality of movable columns arranged side by side are used to block the cable outlet, and a spring is installed at the top of the movable column, effective sealing of the cable outlet is achieved, and it can also be applicable to cables of different shapes and sizes; since interconnected connecting rods and pressing rods are used, and a spring piece is installed on one side of the connecting rod, sealing of the cable outlet is achieved, and it can also be adjusted according to the number and shape of the cables; since a fixed component is used to drive the movable column to move up and down, extrusion fixing of the cable is achieved to prevent the cable from being pulled, and it can also be freely opened or closed as needed.

[0051] Embodiment 1

[0052] The technical solutions in the embodiments of the present application effectively solve the technical problems of poor applicability and ineffective sealing in the use of the existing sealing structure for the cable outlet of a power cabinet. The general idea is as follows:

[0053] In view of the problems existing in the prior art, the present invention provides a sealing structure for the cable outlet of a power cabinet. The sealing structure includes a distribution box body 1 for storing power devices, and a sealing component 2 for sealing the cable outlet on the distribution box body 1. There are two groups of sealing components 2, and the two groups are corresponding up and down, that is, the cables entering and leaving the distribution box body 1 are fixed simultaneously from the upper and lower ends to form a "clamping" state:

[0054] The distribution box body 1 has power components installed inside it;

[0055] The sealing component 2 is installed on the distribution box body 1, and the sealing component 2 is used to seal the cable outlet, block the gap between the cable outlet and the cable, and prevent sundries or insects such as cockroaches and moths from entering the interior of the distribution box body 1;

[0056] Among them, the sealing component 2 includes a fixing plate 21, and a plurality of movable columns 23 are inserted into the fixing plate 21. The plurality of movable columns 23 are arranged in a rectangular array, and a compression spring 24 is installed at the top of each movable column 23. The compression spring 24 is always in a compressed state, which can push the movable column 23 towards the cable outlet direction, so that the movable column 23 "clamps" the cable entering and leaving the cable outlet, and blocks the gap between the cable outlet and the cable;

[0057] The movable column 23 is connected to the fixed plate 21 through a compression spring 24, and the elastic force received by the movable column 23 is always directed towards the wire outlet direction, so that the movable column 23 can stably press against the outer wall of the cable and adaptively change according to the contour of the cable, thereby improving the fitting degree between the movable column 23 and the cable. As Figure 10 shown, it can surround the outside of the cable to ensure that the sealing component 2 can...

[0058] In some examples, the number of the sealing components 2 is two groups, and the two groups of sealing components 2 are respectively located on the upper and lower sides of the wire outlet, so as to "clamp" the cable located inside the wire outlet from the upper and lower directions;

[0059] Among them, the movable columns 23 inside the two sealing components 2 are opposite up and down and fit together, respectively squeezing the upper and lower surfaces of the cable, so as to form a shape opposite to the cable up and down.

[0060] In some examples, a plurality of partitions 25 are equidistantly installed at the front end of the fixed plate 21, and the partitions 25 are located between two adjacent movable columns 23. The adjacent two movable columns 23 are separated by the partitions 25 to avoid mutual influence, and at the same time, the telescopic direction of the movable column 23 can also be restricted;

[0061] Among them, when the movable column 23 is not stressed, the length of the compression spring 24 is less than the length of the partition 25, so as to avoid separating from the fixed plate 21 in the natural state of the movable column 23, thereby ensuring the stability of the movable column 23 during use.

[0062] In some examples, a cover plate 22 is installed at the front end of the fixed plate 21, and the top of the cover plate 22 is hinged to the top of the fixed plate 21, and the bottom is connected to the fixed plate 21 through bolts, which is used to limit the movable column 23 in the fixed plate 21. At the same time, when installing or repairing the movable column 23, only need to open the cover plate 22 to observe the workpiece inside the fixed plate 21, which is convenient for repair and adjustment.

[0063] In the specific implementation process, the two sealing components 2 are respectively fixed on the upper and lower sides of the wire outlet, and the cable entering and leaving the wire outlet passes through between the two sealing components 2. At this time, the movable column 23 inside the fixed plate 21 is squeezed towards the cable direction under the action of the spring at its top, and stops when it touches the surface of the cable, so as to fit with the surface of the cable. Similarly, the two groups of sealing components 2 are respectively attached to the upper and lower surfaces of the cable to form a shape as Figure 10 shown, so as to block all gaps except the cable, thereby improving the sealing effect of the device. Secondly, it can also be automatically adjusted according to the shape of the cable without opening holes of a specific shape. In addition, all cables entering and leaving the wire outlet can be stably "clamped", because no matter how many cables there are, it can adaptively change, thereby improving the applicability of the device.

[0064] Example 2

[0065] In the embodiment of the present application, in order to effectively solve the technical problems that the existing sealing structure of the power cabinet outlet has poor applicability and cannot achieve effective sealing during use, the general idea is as follows:

[0066] The pressing member 4 includes a connecting rod 41 and a pressing rod 42 that are hinged to each other. The pressing rod 42 is inclined towards the direction where the outlet is located, so that the pressing rod 42 can stably press on the cable. Moreover, when the cable is pulled outwards, it can hook the cable to prevent the cable from being easily pulled;

[0067] Among them, a spring piece 43 is installed on the side wall of the connecting rod 41, and the spring piece 43 is attached to the pressing rod 42, providing a downward pressing force for the pressing rod 42, so that the pressing rod 42 presses on the cable under the action of the force. When the pressing rod 42 is in contact with the outer wall of the cable, it stops pressing down, so as to correspond to the outer wall of the cable, as Figure 11 shown, completely wrapping the cable.

[0068] In some examples, one end of the spring piece 43 facing the pressing rod 42 is arc-shaped and fits the outer wall of the pressing rod 42 to provide a downward pressure for the pressing rod 42, and the other end is fixedly connected to the connecting rod 41 to keep the position of the spring piece 43 constant;

[0069] Among them, magnets are installed inside both the pressing rod 42 and the spring piece 43, and the pressing rod 42 and the spring piece 43 are attracted to each other through the magnets, so that the pressing rod 42 can always be attached to the spring piece 43, facilitating the synchronous movement of the two.

[0070] In the specific implementation process, the two pressing members 4 are respectively fixed on the upper and lower sides of the outlet, and the cables entering and leaving the outlet pass through between the two pressing members 4. The spring piece 43 provides a downward pressing force for the pressing rod 42, so that the pressing rod 42 presses on the cable under the action of the force. When the pressing rod 42 is in contact with the outer wall of the cable, it stops pressing down, so as to correspond to the outer wall of the cable, as Figure 11 shown, completely wrapping the cable. Similarly, the two groups of pressing members 4 are respectively attached to the upper and lower surfaces of the cable, forming a shape as Figure 11 shown, thus blocking all gaps except the cable, thereby improving the sealing effect of the device. Secondly, it can also be automatically adjusted according to the shape of the cable without the need to open holes of a specific shape. In addition, all cables entering and leaving the outlet can be stably "clamped", because no matter how many cables there are, it can be adaptively changed, thereby improving the applicability of the device.

[0071] Example 3

[0072] Based on Embodiment 1 and Embodiment 2, in the embodiment of the present application, in order to effectively solve the technical problems that the existing sealing structure of the power cabinet outlet has poor applicability and cannot achieve effective sealing during use, the general idea is as follows:

[0073] The top of the connecting rod 41 is connected to the movable column 23, and the connecting rod 41 and the movable column 23 have the same specifications. By combining the extruding member 4 and the sealing assembly 2, the movement range of the pressure rod 42 can be increased, and at the same time, the outward movement of the cable can be effectively prevented.

[0074] Embodiment 4

[0075] Based on Embodiment 1, the embodiment of the present application effectively solves the technical problem that the cable fixing is cumbersome when the existing sealing structure of the power cabinet outlet is in use. The general idea is as follows:

[0076] The rear end of the sealing assembly 2 is connected with a fixing assembly 3, and the fixing assembly 3 is used to connect the sealing assembly 2 to the outlet, so as to keep the position between the sealing assembly 2 and the outlet stable;

[0077] Among them, the fixing assembly 3 includes a sliding rod 32, and a chute is opened on one side of the sliding rod 32 away from the sealing assembly 2. Two limiting hooks 33 are installed inside the chute, and the two limiting hooks 33 are connected by a spring;

[0078] The spring between the two limiting hooks 33 is always in a compressed state. Therefore, when the two limiting hooks 33 are put into the outlet, the two limiting hooks 33 can be separated from each other under the action of the spring, so as to hook the outlet, so that the fixing assembly 3 is connected to the outlet. At this time, the sealing assembly 2 connected to the fixing assembly 3 is fixed on one side of the outlet together.

[0079] In some examples, a positioning seat 31 is installed at the rear end of the sealing assembly 2, and a lead screw 34 is installed inside the positioning seat 31;

[0080] Among them, the inside of the positioning seat 31 is connected with a threaded cylinder 35 through a bearing, and the threaded cylinder 35 is sleeved outside the lead screw 34, and the two are connected by threads. Therefore, by rotating the threaded cylinder 35, the lead screw 34 can extend out (or retract into) the positioning seat 31. Since the sliding rod 32 is fixed on the outlet through the limiting hook 33, when the lead screw 34 expands and contracts, the sealing assembly 2 can be driven to move up and down synchronously, so as to adjust the position of the sealing assembly 2 and the fitting degree between the two sealing assemblies 2.

[0081] In some examples, two guide rods are installed outside the sliding rod 32, and the guide rods are inserted into the positioning seat 31;

[0082] Among them, the two guide rods are respectively located on both sides of the lead screw 34, and the guide rods are parallel to the lead screw 34, so as to ensure the stability of the expansion and contraction direction of the lead screw 34 and avoid deviation.

[0083] In the specific implementation process, when it is necessary to install the fixing component 3 onto the wire outlet, first press the two limiting hooks 33, so that the spring between the limiting hooks 33 is compressed. Then insert the two limiting hooks 33 into the wire outlet and release them. Therefore, when the two limiting hooks 33 are placed into the wire outlet, the two limiting hooks 33 can be separated from each other under the action of the spring, so as to hook the wire outlet, making the fixing component 3 connected to the wire outlet. At this time, the sealing component 2 connected to the fixing component 3 is fixed together on one side of the wire outlet. Similarly, install the other sealing component 2.

[0084] When it is necessary to adjust the position of the sealing component 2, rotate the threaded barrel 35 (threaded connection between the threaded barrel 35 and the lead screw 34) at the top of the positioning seat 31, which can make the lead screw 34 extend out (or retract into) the positioning seat 31. Since the sliding rod 32 has been fixed to the wire outlet through the limiting hooks 33, when the lead screw 34 expands and contracts, it can drive the sealing component 2 to move up and down synchronously, so as to adjust the position of the sealing component 2 and the fitting degree between the two sealing components 2, facilitating the entry and exit of the cable through the wire outlet (reducing the difficulty of cable installation).

[0085] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
